Kapton is a polyimide film used in flexible printed circuits (flexible electronics) and space blankets, which are used on spacecraft, satellites, and various space instruments. Invented by the DuPont Corporation in the 1960s, Kapton remains stable across a wide range of temperatures, from 4 to 673 K (−269 to +400 °C). Kapton is used in ...
Chemical structure of Kapton, a polyimide. Polyimide (sometimes abbreviated PI) is a polymer containing imide groups belonging to the class of high-performance plastics.With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, such as high temperature fuel cells, displays, and various military roles.
Kapton is a type of polyimide film, has very low outgassing. Kapton is discouraged if a ceramic alternative can be used. [3] Some elastomers have sufficient vacuum properties to be employed in vacuum o-rings: NBRs, (nitrile rubber), commonly used for demountable vacuum seals (bakeable only up to 100 °C).
Kapton (tape) 0.20 [17] Manganese: 7.810 [5] Lowest thermal conductivity of any pure metal. [18] Marble: 2.070–2.940 [5] [19] Expanded polystyrene: 0.033–0.046 [20] Polyurethane foam 0.03 [5] Silica aerogel: 0.02 [5] Silicon nitride: 90, [21] 177 [22] Ceramics material. Silver: 406 [23] Highest thermal conductivity of any pure metal. Snow ...
The emissivity of the surface of a material is its effectiveness in emitting energy as thermal radiation. Thermal radiation is electromagnetic radiation that most commonly includes both visible radiation (light) and infrared radiation, which is not visible to human eyes.
Drawing of a tape-automated bonding carrier and definitions of various parts of the TAB assembly. Tape-automated bonding (TAB) is a process that places bare semiconductor chips (dies) like integrated circuits onto a flexible circuit board (FPC) by attaching them to fine conductors in a polyamide or polyimide (like trade names Kapton or UPILEX) film carrier.
The golden areas are MLI blankets on the Mars Reconnaissance Orbiter. The principle behind MLI is radiation balance. To see why it works, start with a concrete example - imagine a square meter of a surface in outer space, held at a fixed temperature of 300 K (27 °C; 80 °F), with an emissivity of 1, facing away from the sun or other heat sources.
Polyimide Tape is produced up of two separate actions. First is the manufacture of the polyimide film itself and the second is the application of the adhesive backing.Tp learn more about Kapton Tape or Polyimide tape. There is a Great blog full of info for Polyimide tape and how its made
